An ingenius dual catapult that directly hurls a stone from the top and also uses a sling to hurl a second.

Soldiers set the tension on the catapult by positioning the tensioner up and down on pegs before winding tension on the bow. This in effect provides a range adjustment.

All parts separated and well labled. Although maps are not provided, each piece is individually edited to the subaobject level with UV coordinates to provide nice grain for which ever woods an artist would like to build it from.
